Tuning is a waste of money: Tell me i'm wrong

There are obviously a lot of clever people on here. Can any of you comment on the equipment used and the results I achieved on my Dyno run? (This is not a trick question!) I'd really like some input and explanation.

You're comparing graphs from a different RR with different calibrations (so the baseline won't be identical) and with unknown correction parameters on one of them. Also, the load factor looks a little high on your printouts - I wouldn't expect to see 125 until you're over 300hp.

Given all those inconsistencies you might as well pull a figure out of your ar*e, it would probably be just as accurate.

A rolling road can be a very accurate measuring tool, but only if used in the right way. :thumb:
 
They look like a manifold and front pipe to me, so I'll ask again, what are headers?


"Headers" as they are commonly called are performance exhaust manifolds.
Usually made of a tubular material and "tuned" by matching lengths and joining into a collector box to "scavenge" the exhaust gas from the prior firing cylinder.

Much different then a "shared" manifold in design and construction not only visually but in performance.

Perhaps too much of an "American" term for you, but the USA is where most aftermarket performance modifications began....

I guess I was wrong, you don't know everything....still just being passive aggressive...

Educate yourself and come out of the darkness of the diesel soot that clouds your ability to understand...

P.S.

The Brits also understood this as far back and even earlier then the Lotus 49B F1 car...must be merit in not using what you call a "manifold"...

 
The equipment looks top notch as does Bob's knowledge.

The second statement does not necessarily have any bearing on the first (apart from possibly the load rating).

Rolling roads are not 100% identical between installations, and there are a variety of external factors that have to be accounted for. We are missing that information from the graph you are trying to base it against, we don't know what correction and calculation factors were used in the first plots and so cannot compare them to those used in the second (which we do know) to establish how the measurements might relate to each other.

So what can you tell from my charts and the equipment used. ChrisA thinks the Dyno equipment looks good...
 
I know nothing except they tell me that my RWHP is good

Bingo. It's an American slang term being used on an English forum.

The proper term is manifold.

HTH. :)

Once again you couldn't be more wrong based on the subject matter of this discussion.

A "manifold" is a "chamber" in which multiple "ports" merge.
It has no ability to be "tuned" as in an automotive application.
It is usually a cast iron part with no " performance "design as to length of the "runner".

We are discussing performance applications and the terms are accepted globally.

A "header" is also a word that is used in the U.K. and defined and understood in the context of this discussion.

A man of your intellect should know that words as used, even if not originally from that country, become acceptable and adopted as common parlance.

Your continuing ignorance is only due to your extremely poor lack of knowledge of performance modifications.

You're beginning to be a bit clownish, so if you have no interest in performance mods and have nothing to contribute other then a passive aggressive attitude, then perhaps this discussion is not for you :crazy:

Leave it to those that are interested in performance modifications !!!

DM, why do you keep asking what headers are?

You know exactly what they are. Why are you doing this becsuse we all know that when someone posts the answer you will hit straight back with some snide answer.

Yes, it is an American slang term being used on a British (not an English forum)

In the UK we call it a manifold. I have no idea what the 'proper' term is.

Hmm let's analyse that.
Bingo. Almost certainly of American origin.
Slang. Almost certainly of Norwegian origin.
HTH. Almost certainly of American origin.
Proper terms please!!!!!!
 
I'm not sure who thinks they're winding up who on this thread (although I could hazard a good guess), but it all seems like a waste of bandwidth to me...

The point is that I, and others, find the creeping Americanisms used to describe car parts with proper English names irksome and unnecessary as it is essentially slang.

The proper term is exhaust manifold, in this case a four branch manifold.

We get Headers, Rotors, the car going to the Shop, Hood (for bonnet, not roof), valve lifters, etc.

Should we be using Trunk instead of Boot, Back end instead of rear Axle, color instead of colour, etc...

Why not just use the English term or should we just abandon all English and Grammar and go 4 txt spk?

You are quite amusing and by your posting stats probably a lonely man that needs to get a life...

32,092 posts since July 2003 or about 8 posts a day...
You tend to deflect on the subject matter and post that which fails to contribute.
Perhaps because of your limited knowledge???

Pull up your trousers, give your wrists a rest and look outside and see that you live not only in a multi-cultural country but a global society....
Necessary to understand and accept "differences' to survive in today's world.

I'm sure I'm much older then you but have learned to graciously accept change, especially in the world of automobiles...
Over the years I've probably owned and appreciated more "proper" British motorcars then you...
You're on a forum about a German built car....so the "proper' terms that you embrace really mean naught beyond your borders...

Always something new to learn and to remain stagnant and "proper" as you is a waste of what could be a productive life...
I guess you also abhor U.K. citizens that don't speak as you require, perhaps an accent or using cultural terms of their heritage?

More important things besides "Creeping Americanisms" that you should be concerned about...

Curious as to your comments on tomorrow's debate....Lib Dem or UKIP ???;)

Cheers

I understand your frustrations in that respect, but it seems that some others had missed the point.

And don't get me started about their inability to sequence a date properly. Their singular inability to accept that month-day-year is a most inappropriate method causes interminable problems in the business world :rolleyes:
